Pennsylvania German, also known as Pennsylvania Dutch or, simply, Deitsch, is one of the two official languages for use by Urglaawe kindreds.

Much of the lore carried from Europe to Pennsylvania was transmitted through oral traditions in the Deitsch language. Deitsch also carries some pre-Roman features (such as names of some of the months, e.g., February (Hanning)) and other idioms that tie to the heathen past.

The demise of Deitsch has been predicted since the 17th century, yet the language survives and is currently being taught on the University level. Urglaawer are working hard to increase its use and presence in daily life.
